GenRad 1863 megohm meter

The GenRad 1863 Megohm meter is the choice for production and inspection tests on devices with resistances up to 20 Tohms. The GenRad 1863 will measure resistance at any of five test voltages of: 50V, 100V, 200V, 250V, and 500 VDC.

IET Gen Rad 1863 megohmmeter
Stability of calibration in the IET Labs, GenRad 1863 Megohm meter is maintained by use of a four-transistor unity gain amplifier. Stable power supplies and feedback voltmeter circuit minimize drift and time wasting adjustments.
